As long as it's feasible to generate programmatically, because that's what I'm doing with a bunch of fringe bitmaps in a certain popular minor mode.
You can definitely generate SVG’s with sag-mode. For example, to generate a downward arrow:
(let ((svg (svg-create 9 9)))
(svg-polygon svg '((0 . 0) (9 . 0) (4.5 . 9)) :fill "black")
(svg-image svg))
